ATTACHMENT T0 SHOCKING-MACHINES.

Specification of Letters Patent.

Patented May 25, 1920.

Application filed April 16, 1918. Serial No. 228,842.

Toall whom it may concern:

Be it known that I, WILLIAM HAoKLY CHUROH, of the town of Superb, in the Province of Saskatchewan, Canada,have invented certain new and useful Improvements in Attachments to Shocking-Machines, of which the following is the specification.

The invention relates to improvements in attachments to shocking machines, and particularly to an improvement in my previous fully disclosed and described in U. S. Patent 1,240,823 dated the 25th day of September, 1917, and the objects of the invention are to provide an improved form of elevator for taking the sheaves from the binder deck and elevating them to depositing position to the basket; to provide a means associated with the elevator for receiving the sheaves from the elevator and automatically discharging them into the basket and for storing the sheaves during the interval that the basket is dumping, and to provide a means for counting the sheaves as they pass to the elevator.

Vith the above general and other minor objects in view which will become more apparent as the description proceeds, the invention consists essentially in the arrangement and construction of parts hereinafter more particularly described and later pointed out in the appended claims, reference being had to the accompanying drawings in which Figurel represents a plan view of my complete invention.

Fig. 8 represents an interior view of the indicator, the end piece having been removed.

Fig. 9 is an enlarged detailed side view of the driving side of the elevator.

Fig. 10 is an enlarged sectional view through the elevator.

In the drawings like characters of reference indicate corresponding parts in each figure.

The shocking machine as herein disclosed is for the greater part constructed identically to the machine described in the patent hereinbefore referred to, and for this reason I have considered it unnecessary to give a detailed showing or description of the shocker except only in respect to those parts immediately associated with the present improvements.

The shocker frame indicated by the ref erence numeral 1, is carried at the outer side by a driving ground wheel 2, rotatably mounted on the basket shaft 3 which is provided intermediate of its end with a curvilinear portion 4 which carries a sheaf receiving and shock forming basket collector 5.

The ground wheel, as already stated, is rotatably mounted on the basket shaft but it is designed to drive the basket shaft upon the throwing in of an angular lever 6 carried by a crank member 7 secured to the shaft, the lever being designed to engage with the spokes of the wheel 2 so as to carry the shaft around with the wheel. The lever is arranged so that it can be manipulated in the same manner as disclosed in my prior patent, such being by way of a cable 8 which controls the action of a bell crank 9 mounted on the frame and engaging with the lever.

A frame 10 is carried by the shocker frame and co-acts with the lever 6 to control the same and is arranged so that after the wheel with the axle has made one complete revolution the lever 6 will be automatically disengaged and the wheel freed from the shaft. This latter frame 10 is identical to that described in the former patent and referred to and fully described therein.

The inner side of the basket frame is pivotally connected to the binder frame 11, such connection embodying front and rear bars 12 and 13 permanently securedto the inner member 1 of the basket frame and having their inner ends pivotally fastened by means of adjusting bolts 14: and 15 to brackets 14 and 15' permanently fastened to the binder frame. The brackets are each provided with a series of adjusting openings to allow of adjusting the bolts and permitting of the raising or the lowering of the inner ends of the bars. This provision is made to accommodate any adjustment made in the binder as occurs from time to time, dependent on the nature of the crop harvested.

Between the binder deck 16 and the basket collector, I mount an elevator 17 for receiving the sheaves ejected from the deck and carrying them up or elevating them to depositing position over the basket, which, it will be noticed, has an open top, and between the upper end of the elevator and the basket I locate a hopper 18 which receives the sheaves thrown down by the elevator and controls their entering the basket. The elevator and hopper are now described in detail.

19 represents a substantially U -shaped supporting bar having the legs 19 and 19 thereof permanently secured one to the front beam of the shocker frame and the other to an arched truss bar 20 extending between the rear ends of the beams forming the shocker frame. The bar 19 is disposed directly above the longitudinal axis of the basket and it carries the hopper 18 which is preferably formed from sheet metal and presents an open top and bottom and has the side wall 18 thereof, toward the binder, inclined, as best shown in Fig. 2 of the drawings, to direct the sheaves toward the center of the basket collector. The hopper is fitted with a pair of trap doors 21 and 22, the trap door 21 being pivotally secured at 21 to the outer side of the hopper while the trap door 22 is supplied at opposite ends with lever extensions 23 pivotally secured to the hopper at 23 and having their extending ends connected in each instance by means of a link 24 to a lug 24 located on the trap door 21. The trap door 22 is further supplied with a pair of lever extensions 25 which project toward the binder and are connected with parts later disclosed.

From the above arrangement it will be obvious that upon the levers 25 being thrown down the trap door 22 will close and in closing will draw up the trap door 21 through the action of the lever extensions 23 and links 2 1. These trap doors, when open, allow the sheaves to escape from the hopper to the basket and also provide a means for guiding the sheaves to the basket from the hopper. When closed they will obviously stop the sheaves and allow them to collect in the hopper, and at this time I might state that theyare closed by parts later described during the interval that the basket is dumping.

The elevator 17 is now tail.

The bars 12 and 13 carry a platform 26 on which I mount a pair of standards 27 described in deand 27 which are slotted. lengthwise as indicated at 28. The lower end of the elevator is adjustably secured to the standards and has the upper end thereof connected to the hopper and it presents an under conveyer 29 and a top or floating conveyor 30.

The under conveyer is constructed as is usual from side frames 31 and 31 connected by a cross deck 31", and at the opposite ends of the deck I locate conveyer shafts and 32 which are fitted with pairs of chain wheels carrying endless chains 33, the chains being fitted at suitable intervals with cross slats Here it will be noticed that the ascending sides of the chains drag over the top side of the deck 31 while the dcscending sides of the chains are under the deck. The lower end of the lower conveyer is disposed at an obtuse angle to the body part thereof and is arranged such that the sheaves ejected from the binder deck 16 will be deposited directly onto the ascending side of the said conveyer at such lower end.

Owing to the bend or turn at the lower end of the under conveyer, it is necessary to supply idler wheels to carry the chains. These are indicated but are not described more fully as they serve the ordinary function.

The conveyer shaft 32 is connected to the upper inner corners of the hopper by means of a pair of swinging links 35 and 35' and the lower end of the conveyer is adjustably mounted in the standards by means of adjusting bolts 36, the bolts when loosened being free to travel in the slots to effect the required adjustment.

The upper or floating conveyer comprises the usual sides 37 and 37' and the connecting deck 37*, and. it is here to be noticed that the sides of the floating conveyer pass to the outer sides of the under conveyer and that the deck is on top, so to speak.

The floating conveyer is swung by upper and lower pairs of links 38 and 39 from the sides of the lower conveyer, the links allowing the floating conveyer to swing away from or close into the under conveyer ac cording to the feed. The links 38 are fitted with extensions 38 and springs 10 are inter posed between the upper ends of the extensions and the body of the lower conveyer, which act to normally hold the floating conveyer in against the under conveyer.

The floating conveyer presents end shafts l1 and l2. carrying rollers fitted with a continuous belt 43, the top side of the belt passing outside the deck 37* and the edges of the belt being contained normally within the sides of the lower conveyer. The conveyers are both driven by the wheel 2 *hich, when the machine is in use, is turning continuously. The said wheel is provided with a chain wheel 4A which carries a chain 45 opcrating a chain wheel 46 located on the outer end of a driving shaft 46' suitably mounted on the front end of the shocker frame. The inner end of the shaft 46 is supplied with a beveled pinion 47 which meshes continuously with a beveled pinion 47 located at the for: ward end of the counter shaft 48 suitably mounted in bearings extending from the inner side of the beam 1 of the shocker frame.

49 represents a chain wheel secured to the shaft 48 and connected by means of a chain 49' with a driving chain wheel 50 secured to the end of the conveyer shaft 32 and providing a drive for the under conveyer 29. The shaft 42 of the floating conveyer is driven by a series of chain wheels, chains and gears directly from the shaft 32, the chains, chain wheels and gears being arranged so as not to interfere with the swing ing movement of the floating conveyer and so as to effect the driving, in an upward direction, of the inner side of the floating conveyer.

From the above disclosure it will be apparent that the elevator is continuously driven and that as the sheaves are ejected from the deck they will be carried directly up between the opposing ascending sides of the floatin and under conveyers and will be delivered from these conveyers directly into the hopper. Further it will be apparent, that the floating conveyer can accommodate itself to a heavy or light feed as required, depending on the nature of the crop, this b reason of the links and springs.

The trap doors of the hopper are controlled by parts now described so that they are closed when the basket is dumping and opened automatically when the basket returns to initial position. To accomplish this I provide two upstanding rocker arms 51 and 52 pivotally mounted on the shaft 48 and having their upper ends adjustably connected as indicated at 53 to levers 54 attached pivotally to the rear ends of the extensions 25.

On the underside of the inner beam 1' of the shocker frame I mount pivotally a short shaft 55 provided with a striker 56 extending inwardly toward the basket and with a downwardly extending lever arm 57 which has the lower end connected by a link 58 to a rod 59 carried by the lower extremities of the rocker arms 51 and 52, it being here noted that the rod 59 is in a location considerably below the shaft 48.

The inner end of the basket shaft is fitted with a sleeve 60 carrying a controlling flange 60 having a flat side 60 and the rocker arms carry a cross bar 61 which is positioned above the shaft 48 and is arranged. to work in conjunction with the flange. In

the open position of the gates and the normal sheaf receiving position of the basket, the bar 61 is adapted to lie on the flat side of the flange, which position is best shown in Fig. 3 of the drawings. Naturally the gates maintain an open position, under the action of gravity, and they keep the bar 61 on the flat side of the flange unless otherwise disturbed.

Upon the attendant dumping the basket, however, the striking plate 62 carried by the basket engages the striker- 56 and by doing so causes the lower ends of both the rocker arms to be swung toward the binder and the upper ends to be swung in the opposite direction sufficiently far to effect the closing of the gates through the action of the levers 54, extensions 25 and links 24. Coincident with this movement the cross bar 61 is swung inwardly over the sleeve and clear of the flange, and in the continued turning movement of the basket becomes automatically locked behind the flange so that it is impossible for the gates, which are then closed, to open. The gates consequently remain closed and locked. closed until the basket completes its revolution to bring the flat side of the flange back to the original position. Immediately this occurs the weight of the gates and sheaves within the hopper operate to throw down the gates and return the parts associated therewith to the original position, which is with the bar 61 directly above the flat side of the flange.

From the above it will be apparent that during the whole interval that the basket is dumping the sheaves which are being ele vated by the elevator are being caught and retained in the hopper and that as soon as the basket returns to its initial sheaf receiving position the gates are automatically released by the basket and the sheaves are freed to pass into the basket.

It is desirable in shocking machines for the attendant to know just how many sheaves are in his basket at the time he wishes to dump it, and for this purpose I provide on 63 in which I mount a short shaft 64 carrying a hand, pointer or indicator 65, the hand operating over a scale 66 having spaced and numbered marks thereon to indicate the number of sheaves. In the drawings the hand is set as pointing to the zero mark. However, upon it being thrown to the left it will point at one or other of the divisions and if it goes six divisions, will indicate six: sheaves, this number being directly opposite the sixth divisional mark.

A stop pin 67 limits the movement of the hand in the right hand direction and prevents it from turning in that direction past the zero mark, and the hand is normally constantly turned toward the zero mark by the action of a coiled spring 68 passing around the shaft and having one end secured to the inner side of the casing and the other end made fast to a pulley 69 permanently secured to the shaft.

On the pulley I Wind a cable, cord or such like 70 which has one end made fast to the pulley and theother end projected over a pulley-71 and extending from the indicator to a counting mechanism 7 2 located on the side of the elevator. The, cable is wound on the pulley so that when it is drawn off it acts to wind up the spring, with the result that when the cable is wound and released the spring immediately throws the hand back to the stop pin and resets it at zero. The indicator is preferably secured to the rear end of the inner beam 1 of the shocker frame so that it can be readily seen by the attendant on the binder at all times.

The counting mechanism comprises a drum 7 3 located on a short spindle 74 and formed integral with a ratchet wheel 75, the teeth of the ratchet wheel being controlled by the action of a pair of specially designed spring pressed pawls 76 and 77. The cable v70 is fastened to the drum, the arrangement being such that when the ratchet wheel is turned in the direction indicated by the applied arrow, (see Fig. 5) the cable will be wound on the drum 7 3 and will operate to pull in a direction to swing the pointer to the left, (see Fig. 7).

The pawl 76 is pivotally carried by a bail bar 78 spanning the drum and ratchet wheel and mounted on the shaft 74 and the bail bar is conneetedby means of an actuating rod 79 to the lower end of an operating crank 80 located at the rear end of a cross shaft 81 positioned above the lower end of the under conveyor 29. The shaft 81 is provided with extending fingers 82 which are normally positioned so that they are struck by the sheaves passing from the deck to the conveyer, with the result that each time a sheaf is ejected from the deck the shaft is turned and the crank operates to swing the bail bar and draw the pawl 76 back one tooth displacement on the ratchet wheel 75.

A spring 83 eo-aeting with the crank 80 is provided to reset the fingers 82 after a sheaf has passed and operates further to effeet, in this resetting action, a pull in the rod 79 and the turning of the ratchet wheel in a counter clockwise direction one tooth displacement. The pawl 77, obviously, acts to prevent the ratchet wheel from turning during the interval that the pawl 76 is being thrown back to catch the next tooth.

From the above disclosure it will be apparent that as the sheaves pass to the elevator the counting mechanism will be actuated one tooth displacement for each sheaf and this movement winds up the cable an amount sufficient to turn the hand each time one division on the indicator. However, it is desirable that each time the basket is dumped the indicator be reset at the zero mark, 'and to this end I provide an action actuated by the binder and controlling the pawls, which effects the release of the pawls from the ratchet wheel the instant the basket starts to dump. This action comprises, (see Fig. 3) a rod 84: rotatably mounted on the underside of the beam 1 of the shocker frame, which rod is fitted at one end with a striker 85 and at the other with a crank 86, the striker being turned inwardly toward the basket so that it will be engaged by the member 62 hereinbefore referred to.

The crank 86 is connected by means of a rod 87 to a controlling lever 88 pivotally secured at 89 to the side of the elevator. The lever is supplied with a pair of flanges 90 and 91 which normally bear lightly against the free ends of the pawls and are arranged such that when the lever is swung by the rod 87 in a counter clockwise direction the pawls are both simultaneously disengaged from the ratchet wheel. The turning of the said lever in the direction aforesaid is effected by the striker plate 62 hitting the striker 85 and effecting an up-push of the rod 87 sufficient to swing the lever to disengage the pawls. The instant the pawls are disengaged the ratchet wheel is free and accordingly the hand 65 will be instantly thrown back to the zero position by the nation of the spring 68. In this connection it is pointed out that this movement occurs very quickly as the ratchet wheel is only released a very short interval owing to the fact that it only takes the plate 62 a very short time to strike and pass the trip 85. Further, this action has to'be quick for the reason that the counting mechanism has to be in the set or counting position before a sheaf can pass as all sheaves ejected actuate it.

While I have described this indicator and the mechanism for operating it in detail, it will be readily understood that various parts can be readily modified without in the least parting from the spirit of the invention, and as covered under the scope of the appended claims.

lVhat I claim as my invention l. The combination with a shocking machine frame, an open topped sheaf receiving and shock forming basket pivotally secured to the frame, means for dumping the basket to deposit the shock and an elevator located to one side of the frame and with the upper end thereof overhanging the basket, of a hopper suspended between the elevator and the basket and adapted to receive the sheaves elevated by the elevator and deliver them into the basket and means actuated b the basket adapted to close the hopper an prevent the delivery of sheaves to the basket during the dumping operation.
